Novak Djokovic and coach Boris Becker are splitting up after three years and a half-dozen Grand Slam titles.
Djokovic posted a statement on Facebook on Tuesday, saying the duo "jointly decided to end our cooperation."

"The goals we set when we started working together have been completely fulfilled, and I want to thank Boris for the cooperation, teamwork, dedication and commitment," Djokovic's posting said.

"On the other hand, my professional plans are now directed primarily at maintaining a good level of play, and also to make a good schedule and new goals for the next season. In this regard I will make all future decisions."Of Djokovic's 12 career major singles trophies - trailing only Roger Federer's 17 and Pete Sampras and Rafael Nadal with 14 apiece - half came while working with Becker.

Djokovic also was runner-up at three Grand Slam tournaments during his time with Becker, meaning the Serb made it to the finals at nine of the 12 majors during their partnership.

At Roland Garros, Djokovic was asked about working with Becker, who was a dominant force in the 1980s and '90s and part of a recent wave of past greats who signed up to coach current stars.

After Djokovic's triumph in Paris, his season went sideways.

Djokovic made an earlier change to his coaching team towards the end of the season with Spaniard Pepe Imaz joining him for the Paris Masters, where the four-time champ-ion fell in the quarterfinals, and for the World Tour Finals in London, where Djokovic lost to Murray.
